Title: Improved apparatus for casting metals
IPC: B22D17/00
Filed: 1927-06-28
Abstract: 299,489. Wade, H., (Wheeling Stamping Co.). June 28, 1927. Discs.-Non-ferrous slugs, for making articles by extrusion, are cast in moulds carried by a rotating table, the castings being rolled after ejection. The moulds 22, Fig. 2, are carried by two tables T intermittently rotated through the distance of two moulds by Geneva mechanism 19. 6 from a shaft 7. The moulds 22 have movable bottoms 24, Fig. 11, held down by springs 26 and covers 37 coupled in pairs to a telescopic slide 28 with a bowl 41 adapted to engage a fixed cam 76, Fig. 2, so as to press the covers down firmly during pouring and cooling. The moulds are filled in pairs by nozzles 85, Fig. 4, which align with the holes in the covers 37, and each receive a charge of metal 77<1> contained in a rotary plug 77 which is adapted to communicate alternately with a melting pot 80 and with an opening 84 to the atmosphere or a non-oxidizing gas supply. The volume of the charge 77<1> may be varied by a. screw 86. In a modification a plug 114, Fig. 26 is reciprocated in a fixed cylinder 78<1> with passages, not shown, which communicate with the melting pot and the nozzle. In the opposite end of the cylinder slides a plug 113, loosely connected by rods 117 and nuts 119 to the plug 114 so that as this moves down it draws in a charge of metal 120, dependent on the positions of the nuts 119, then both pistons move to close the passage to the pot and open that to the nozzle. The return of the piston 114 first forces out the charge and then by direct contact returns the piston 113. When the moulds approach the discharge station the bowl 41 is released from the cam 76 and then when a pair of moulds stop at each discharge station cams on shafts 42, driven by chains 46 from the shaft 7, actuate slides 57 and 52 which litt the covers 37 and the bottoms 24 so that the hot blanks B can be thrown by cam-operated ejectors 63 into shoots 70 whence they are conducted to flattening rolls 72. If desired the covers may be raised at the station proceeding the discharge and in that case they are retained by ball catches 59, Fig. 9, or they may be raised by an extension of the fixed cam 76 acting on the bowl 41. The plugs 77 are rotated by linkwork 92, 93, 97, 98 and cams on the shafts 42, and are each adjusted axially to take up wear bv a collar 89, Fig. 6 which screws on a fixed sleeve 78 and engages between a flange 87 and a collar 90 secured on the stem of the plug. The moulds are cooled by fluid such as air delivered through perforated pipes arranged above them and the nozzles 85 are heated by burners b.

Title: Distillation of liquids
IPC: B01D5/00
Filed: 1937-06-24
Abstract: In a process of fractional distillation by multiple effects, the liquid traverses each effect successively in inverse order of its condensation effects, the process comprising heating and partial distillation of the liquid, recovery of the latent heat of evaporation of the fractions evaporated in the preceding effect (considering the order of the effects to begin with that of highest temperature) by condensation, and partial recovery of the specific heat in the final residue and in the condensed fractions produced in the previous effects.  Differences of pressure are maintained between the successive effects by means of a gravity head or by a pump. Apparatus for the process comprises a series of <PICT:0499586/III/1> <PICT:0499586/III/2> <PICT:0499586/III/3> <PICT:0499586/III/4> chambers T1...T5, the raw liquid entering T4 through pipe a4 and heater R5 and passing up through a spiral channel Z4 formed by spirally-arranged collecting pipes 12 for the condensed fractions. It then passes over a spiral tube S4 containing heated vapours fed by pipe X4 from the next chamber T3.  The heated liquid then passes from T4 to T3 by pipe a3, pump B3 and heater R4, where it follows a similar course between collecting pipes 15 and over a coil S3 fed with hot vapours from the next chamber T2.  Part of the liquid is evaporated in T3 and passes by pipe X4 to coil S4 in T4, the remainder passes by pipe a2 and heater R3 to chamber T2 where it passes over collecting pipes 17 and coil S2, where part is evaporated and passes by X3 to coil S3.  The residue then passes by a1 and heater R2 to T1 where another fraction is evaporated and passes by X2 to coil S2.  The liquid then passes by pipe a and heater R1 to a boiler containing tubes 20, 24 in which the liquid is heated by a furnace, the vapours passing off by pipe X1 to coil S1, while the residual liquid is run off by pipes 30...42 to heat the heaters R1...R5 and is finally cooled in a cooler R6. The coils S1...S5 work a successively lower pressures, and during their spiral passage through these coils the condensed vapours are flung by centrifugal force to the outer peripheries of the coils, where they are collected by tangential pipes z..zx, to be used for heating the heaters R1...R5.  The pipes z...zx passdown the chambers T1... T5 on the outer sides of the coils, are gathered into spiral collections 12, 15, 17, 19, and leave the chambers T1...T5 at the bottom. Air traps may be arranged on the pipes z... zx to separate uncondensed vapours. Specifications 490,703; and 499,024, [Group II], are referred to.

Patent GB-182116-A (GB)
Abstract: 182,116. Siemens & Halske Akt.-Ges. Jan. 21, 1921, [Convention date]. Automatic exchange systems.-In a system in which the selection of an i d l e group-selector G, capable of extending a call in the desired direction, is effected by an auxiliary switch D, which responds to the first set of impulses, and non-numerical switches V, P, as described in Specification 174,365, a differential relay Si makes the selector G non-available when the number of available lines in the wanted level is equal to the number of selectors which are about to extend a call in that level. The common test circuit for the switches P, V includes a contact 49 of the relay Si, of which the winding II is earthed through as many resistances 131 - - 140 as there are outgoing lines in the wanted level, say ten. The winding I is earthed through a resistance 95 for each engaged line in the group, and is also earthed through a relay E<2>, of similar resistance, of each switch P during the interval between the selection of the group-selector by the switches P, V, and the extension of the calling line by the selector G to a. connector LW. When the number of switches P in this condition equals the number of free outgoing lines in the wanted level, the number of resistances 95 and relays, such as E<2>, connected to winding I equals the number of resistances connected to winding II and the relay Si de-energizes, opening contact 49 and thus preventing any more P-switches setting themselves on to this group.

Patent GB-596613-A (GB)
Title: Improvements in manufacture of organo-siloxanes
IPC: C08G77/00
Filed: 1945-07-17
Abstract: A mixture of compounds having the general formula CH3SiX3 and (CH3)3SiY, where X and Y are halogens or alkoxy radicals and may be the same or different, in such proportions that the ratio of methyl radicals to silicon atoms in the mixture is between 1.05 and 1.3 is hydrolysed, the products condensed by heating below 100 DEG  C. in an aqueous acid medium with pH between 0.3 and 2.0 until they contain 0.3-5 per cent of hydroxyl groups, and the methyl silicon condensation product, which is mouldable and thermosetting, separated.  The products are particularly suitable for the production of glass laminated material in conjunction with glass fibre network. They may be cast at 200 DEG  C. followed by heating for 25-50 hours at 150 DEG  C. to yield transparent bodies transmitting light down to 2150 A DEG .  They may also be used, preferably with glass, asbestos or cotton cloth for electrical insulation, and in solution in alcohol, toluene, aromatic naphthas or mixtures of alcohols and hydrocarbons as impregnants.  In the example, a mixture of 9 mols. of monomethyltriethoxysilane and 1 mol. of trimethylmonoethoxysilane were added with stirring to a dioxane-water solution containing more than sufficient water for complete hydrolysis and sufficient hydrochloric acid to make the pH 0.97.  The mixture was then kept at 60 DEG  C. for seven hours, diluted with water and the tacky layer separated and dissolved, in benzene, the solution washed and dried and the benzene evaporated off.  Heated at 200 DEG  C. the product became insoluble and infusible.  The acid may be added in a series of steps throughout the condensation reaction.  The dioxane may be replaced by ethyl alcohol, diethyl ether or benzene.  An example is given of the preparation of a laminated glass fibre cloth.  In another example, to a 65 per cent benzene solution of the siloxane were added asbestos, boric acid and calcium stearate, the mixture was milled, dried and ground and yielded a moulding powder.  Other fillers mentioned are aluminium metal powder, carborundum, iron powder, blue lead, zinc oxide, magnesium oxide, hydrated alumina, anhydrous alumina, barium carbonate, copper powder, pumice powder, a diatomaceous earth known as "Celite" (Registered Trade Mark), or a hydrated calcium silicate.  Directions are given in the Specification for determining the hydroxyl content of the thermosetting products.
